Tracker One Thermistor

I’m seeing readings from the Tracker One’s internal thermistor that are significantly higher than ambient (as much as 20+° F). I assume others are seeing this as well, and it’s a result of the virtually air-tight package. So the thermistor isn’t suited for tracking ambient temp, just Tracker One internal temp? (I’m sure this is true, but my client wanted me to verify.)

That is correct. Because the case is sealed, the components inside generate heat, and it’s black, it can be considerably warmer than the ambient temperature.

For ambient temperature, we recommend an external temperature sensor. You can add your own to the M8 connector, and we have a M8 temperature and humidity sensor available pre-made.
